Study of Cellphone Use Finds a Link to Cancer

We have been debating for a long time whether or not cellphone use can cause cancer. On Thursday, the National Toxicology Program, a part of the US Department of Health and Human Services, concluded what experts called the world’s largest and most expensive experiment to determine whether or not cell phones are a cause of cancer.

The study began during the Bill Clinton Administration and it cost over $30 million and involved over 3,000 rats. The experiment ended on a positive note but found that some types of cell phones raise the chances of brain cancer developing in male rats.

John Bucher, a scientist with the National Toxicology Program, said in a statement to the New York Times that there is a link between radio frequency radiation and tumors in male rats.

He did warn us that the exposure levels and durations that the rats endured are far greater than what humans typically encounter and that this study could be used in comparison to the human’s experience.

Experts, however, are arguing that even a small demonstrated rise in cancer risk could be devastating, with billions using cell phones on a daily basis.

The lowest level that was used in the study was equal to the maximum amount of radiation allowed by the government, and that level rarely occurs in typical cell phone use. The highest level was four times the limit allowed.

So, in the end, the study was very beneficial to our futures, as we do need to know how much radiation is too much for human use. Hopefully, we can create a more powerful phone with less radiation, but that will be determined by the government regulations and what we want in our phones.

Tattoos are a sign that you’re healthy

According to the American Journal of Human Biology, a new study suggests people with more than one tattoo have better immune system responses to new tattoos than those who are getting tattooed for the first time.

The research states that the act of getting a tattoo activates the immune system in a way that can be compared to getting a vaccination, making one less susceptible to future illnesses. Although the study is small and needs some development, it does enlighten us to how the body can be trained to react to stress over time.

“The research states that the act of getting a tattoo activates the immune system.”

The study included researchers from the University of Alabama, who retrieved saliva samples from 29 different volunteers before the received tattoos and after they were given. Nine of the 29 volunteers were first-time tattoo recipients. The researchers analyzed the saliva samples for “immunoglobulin A, which is an antibody that lines the gastrointestinal and respiratory systems, and cortisol,” a stress hormone known to lower immune response.

After analyzing the data, the researchers discovered that the volunteers who had never received a tattoo had a much lower immunoglobulin A level than those who have had tattoos before. This could suggest that people who have had more experience with tattoos have an immune system that is more prepared for stress of that caliber.

“They don’t just hurt while you get the tattoo, but they can exhaust you,” Lynn, one of the lead researchers, said in the release. “It’s easier to get sick. You can catch a cold because your defenses are lowered from the stress of getting a tattoo.”

Lynn says that someone getting a tattoo for the first time is like an out-of-shape person exercising at the gym. One’s muscles are sore at first, but the pain reduces after one exercises enough.

Although there are some problems with this study, the fact that some people could simply have better immune systems than others or the fact that getting a tattoo can be dangerous if one goes to a tattoo shop which is careless with their instruments,causing infection, Lynn hopes the study can reduce the stigma that surrounds getting tattoos and hopes others won’t judge so harshly when viewing a person with tattoos.

New nicotine vaccine could help smokers quit

According to data collected by the American Cancer Society, 70 percent of smokers want to quit altogether, 7 percent actually succeed at quitting smoking their first time, and 3.5 percent quit smoking cold turkey. These statistics are already extremely unsettling. Even though 40 percent of smokers tried to quit in 2015, half of smokers will relapse into smoking while intoxicated with alcohol.

These statistics even come into play with individuals who are underage. According to data collected by the Centers for Disease Control, 80 percent of smokers began smoking before the age of 18, while 90 percent began smoking before the age of 21. 3,900 teens begin smoking each day, totaling 600,000 teens each year. What’s disturbing is that 11 percent of middle school students reported having smoked. That means 11 percent of pre-teens between the ages of 11 and 14.

A successful vaccine to assist individuals in quitting smoking for good has been difficult to discover. According to a report in ACS’s Journal of Medicinal Chemistry, a new vaccine for quitting smoking has been designed.

Over half of smokers who want to quit will not succeed in quitting their first time. There are several ways to quit smoking available. Smokers can quit cold turkey, use behavioral therapy, nicotine replacement therapy (nicotine gum, patches, inhalers, spray, and lozenges), and medicine like Zyban and Chantix. These tools are readily available, but aren’t always effective, and may even have undesirable side effects.

This new vaccine design would target the nicotine molecule directly. Two individuals participated in a clinical study of the vaccine which ultimately failed. However, the clinical study provided worthwhile pieces of information, that scientists could improve upon.

The trials indicated that the individuals who produced the most elevated amounts of anti-nicotine antibodies were more likely to refrain from smoking for more than six months. Kim D. Janda, Ph.D., and fellow researchers from The Scripps Research Institute wanted to expand on this discovery.

The team designed a new vaccine that could raise the amount of antibodies that could attach to nicotine molecules.

While testing in mice, they discovered that the vaccine deferred the effects of nicotine after injection within the initial 10 minute period. Additionally, they discovered that the mice treated with the vaccine had lower concentrations of nicotine in their brains, which is where nicotine has its effects. The team expressed that their future endeavors will concentrate on further perfecting the formula of the vaccine to prepare it for potential clinical studies.

The importance of vitamin D

When we think of vitamin D, we think of the vital nutrient supplied by the sun to nourish our bodies. While it’s true the sun is a major source of vitamin D, we must remember that during the short, cold days of the winter months it’s less likely that we are going to absorb the proper dosage. Therefore, you may want to consider vitamin D supplements. Continue reading The importance of vitamin D
